I might actually have one. I had to replace the whole cassette on the Ascot (my spare P38) and kept the glass. I gave it to a friend who was restoring a Classic LSE but we found that the Classic glass is flatter so it was no good for him. This was a couple of years ago and he was able to get a new seal then but I'm pretty sure he still has the P38 glass in his workshop. I'll give him a call and ask. No idea how it could be got to Italy in one piece though.....

Thanks a lot for your offer @Gilbertd, I'm awaiting a response from a couple of scrappers here who appear to have P38s to take parts from.

Personally I would quite happily have the sunroof sealed up. I like having the extra illumination from a window in the roof but why on earth would you want to have a noisy breeze coming in the car from above? There is a perfectly decent climate control system built into P38 that provides fresh air at the desired temperature.

We found it most useful when feeding the giraffe at the safari park.

Richard, thanks for the information. I just couldn't visualise what it looked like !

Velvet, you are right about not being able to find a new seal - I tried a number of different places that I have ordered from in the past, in the US, the Ukraine, and a few other places but there is nothing available anywhere.

Gilbertd made a good suggestion, that it is possible that a BMW seal might work being as BMW owned Range Rover at this point in time, and the may just have used sunroof parts from a 5 series or a 7 series. A long shot, I know, but you just could be lucky. I am going to measure my sunroof and then make a few enquiries over the new few weeks.

Yes Pierre, this could be the way...I looked among the BMW seals but at the moment nothing seems to have a profile like that on the P38, which as I wrote yesterday seems to share the sunroof with late RR Classics (the part number is the same). The one that comes closest is for the E30 series but it's still not the same and I doubt it will work.
It would be great to find an alternative, the hunt continues.

As it is a Webasto sunroof afaik maybe the manufacturer can help?

I don't know, maybe that's a possibility. In the meantime I took the glass off and probably found the reason for the bigger leaks. In fact the glass has separated from the metal shell. There is no gasket between the glass and the frame, the seal is ensured only by the sealant which dries up over time and heat and, losing adherence, allows water to pass through. I'm proceeding with the restoration of the frame and the re-gluing of the glass.

Update: sunroof frame was brushed and painted, glass was reglued and seal was cleaned and treated.
Sunroof in the car again, for the moment no leaks. Also checked the four drain tubes, all free and working.

(yes I know, the Rangie deserves a respray)
